Definitions

  • the invention relates to a system for flue gas purification having a metering device for a purifying agent, and to a method for feeding a purifying agent for a system of this type for flue gas purification to a metering device.
  • a consumable substance is generally used as purifying agent for purification of the flue gas.
  • This substance is, for example, a sorbent, which is supplied as a bulk material.
  • a typical example of a sorbent is, for example, what is known as oven coke.
  • the purifying agent is generally supplied to the system in a storage container, which in the case of oven coke is typically what is known as a “big pack”.
  • the purifying agent is fed to a purification unit in metered form.
  • a metering device is provided.
  • the purifying agent is in turn fed to this metering device via the storage container.
  • the storage container is sufficiently large to cover the demand for a purifying agent for a relatively long period, for example a number of days.
  • this container has to be replaced with a full one. Because of the size of the storage container, this is generally carried out with the aid of a fork-lift truck, by means of which the full storage container is transferred to the metering device after the empty storage container has been removed. This takes up a considerable amount of time.
  • the present invention is based on the object of making it easy and inexpensive to change the storage containers.
  • the object is achieved by a system for flue gas purification, having a metering device for a purifying agent, which can be fed to the metering device from a storage container, in which system there is a collection device for receiving a plurality of storage containers, by means of which collection device the storage containers can automatically be moved to the metering device.
  • the option of automatic movement produces the advantage that a complex, time-consuming manual exchange of the storage containers is not required.
  • the number of interventions required on the part of the operating staff is significantly reduced, since a plurality of storage containers can be held in the collection device, so that overall the quantity of purifying agent in the collection device is sufficient for a very long period, during which no intervention is required on the part of the operating staff.
  • the need for an additional store next to the collection device is eliminated.
  • the collection device preferably has a conveyor unit for moving the storage containers. Therefore, the conveyor unit is used to convey the corresponding storage container out of the collection device or within the collection device to the metering device. This conveyor unit is preferably at the same time also used to automatically remove an empty storage container from the metering device.
  • the collection device therefore fulfills a dual role, namely that of storing a plurality of containers and that of automatically conveying them.
  • the conveyor unit is designed as a distribution rail, from which the storage containers can be suspended. This makes it easy to move the storage containers.
  • the storage containers may also be placed onto a conveyor belt or conveyor rolls.
  • the conveyor unit prefferably be of revolving design, in order to allow simple exchange, i.e. removal of the empty storage container and supplying of the full storage container.
  • the conveyor unit is preferably configured as a rotatable unit with load-bearing arms in the manner of a revolving magazine, in which case a storage container can be suspended from each of the load-bearing arms. Rotation of this rotatable unit results in the storage container being changed over.
  • the corresponding storage container can preferably be fed to the metering device from above, in order to make use of the force of gravity. Further auxiliary means or lifting tools for feeding the purifying agent to the metering device are not required.
  • a guide element for guiding the storage container during the movement to the metering device.
  • the purifying agent is preferably a bulk material.
  • it is a sorbent, such as for example what is known as oven coke.
  • the storage containers are preferably what are known as “big packs”.
  • the object is also achieved by a method for supplying a purifying agent for a flue gas purification system to a metering device, in which a plurality of storage containers holding the purifying agent are received by a collection device, and a storage container is fed to the metering device automatically.
  • FIG. 1 shows a highly simplified illustration of a system for flue gas purification having a collection device
  • FIG. 2 shows a plan view of the collection device shown in FIG. 1, and
  • FIG. 3 shows a further embodiment of a collection device.
  • a system for flue gas purification 2 as shown in FIG. 1 comprises a collection device 4 , in which a plurality of storage containers 6 , which are used to store a purifying agent R, are arranged.
  • the system 2 also has a metering device 8 , which is designed as a metering screw, and a flue-gas purification region 10 , to which the purifying agent R is supplied from the metering device 8 .
  • the flue-gas purification region 10 generally comprises a multiplicity of components which interact in a system for flue gas purification 2 in order to purify a flue gas RG.
  • This flue gas RG is fed to the flue-gas purification region 10 and leaves it as clean gas G.
  • the purifying agent R is consumed and a remainder material RS, which is discharged from the flue-gas purification region 10 , is formed.
  • the storage containers 6 in the collection device 4 are suspended from a distribution rail 12 , which is secured to a supporting structure 14 .
  • a guide element 16 in the form of a guide rail or a guide bar. This guide element 16 ensures that the corresponding storage container 6 , which is being fed to the metering device 8 , is positioned accurately above a filling funnel 18 of the metering device 8 .
  • an outlet barrier 20 which in the closed position prevents the purifying agent R from escaping from the storage container 6 , to be opened automatically.
  • the empty storage container 6 is automatically replaced with a full storage container 6 .
  • the storage containers 6 are moved along the distribution rail 12 with the aid of a motor drive (not shown in more detail).
  • the distribution rail 12 it is preferable for the distribution rail 12 to be designed as a revolving distribution rail 12 , as can be seen from FIG. 2 .
  • the system automatically registers when the corresponding storage container 6 above the metering device 8 is empty.
  • a suitable sensor element 22 which in the exemplary embodiment shown in FIG. 1 is designed as a filling-level measuring device on the filling funnel 18 .
  • this sensor element 22 it is also possible to design this sensor element 22 as a weight sensor and to arrange it, for example, on the distribution rail 12 , in order to measure the weight of the corresponding storage container 6 .
  • the sensor element 22 emits a sensor signal S to a control unit 24 , which transmits a motor signal M to the motor (not shown) for the distribution rail 12 , in order to activate the motor when the storage container 6 is empty.
  • a system 2 of this type has the significant advantage that, firstly, the purifying agent R is fed to the metering device 8 automatically. If the control device 24 and the sensor elements 22 are provided, the supply of the purifying agent R to the metering device 8 is fully automated. Consequently, there is no need for any intervention on the part of the operating staff, and changing the storage container 6 is an inexpensive operation. Secondly, there is no need for an additional store, since the collection device 4 holds a number of storage containers 6 .
  • a conveyor unit as shown in FIG. 3 is designed as a rotatable unit 26 having, in the exemplary embodiment, four load-bearing arms 28 .
  • the storage containers 6 are suspended from the load-bearing arms.
  • the storage containers 6 are exchanged by way of a rotation of the rotatable unit 26 .
